As a result, many linguists have connected the region's speech patterns to the notably similar patterns of Latin America.

Several similarities appear to support this connection, which is referred to as la teoría andalucista among these shared features are seseo, the aspiration or elision of syllable-final /s/, the weakeing of /x/ to [h], and the omisión of intervocalic /d/.
